Intelligent Door Lock

an advanced access control system

The Intelligent Door Lock employs an entrance code to control access to certain rooms or buildings. The heart of the system is a microcontroller manufactured by Atmel. The system employs an electric door latch and has visual and acoustic indicators for ease of use and your personal safety. Access codes are stored in a non-volatile memory device.The flexibility of the system is due to a microcontroller running a program written specifically for the purpose of controlling access to rooms, apartments, hallways and complete buildings.. An all-hardware version of such a system would be much complex and costly. The use of an EEPROM allows access codes to be stored without having to worry about loss of data due to power supply failures.The access codes can easily be reprogrammed by switching the system into ‘supervisor mode’, as will be discussed further on.
